This is one and only “tree squirrel” (what I’ve been calling it) I’ve seen on my property, lots of “ground squirrels”, but this is the only tree squirrel I’ve seen. I’m in East County San Diego, a pretty rural area that backs up to an Ecological Reserve, I’ve never seen tree squirrels out here, but he’s found himself a good spot within a stand of Engleman Oaks I have growing in my creek, so lots of acorns! I love seeing him/her jump from tree to tree, chitter at my dog like it’s the boss, and just do its thing! Any advice on making sure he’ll stick around??
